Abstract (en)

[origin: EP0477834A1] A vacuum hoisting device for transporting loads having an adhesive surface has at least one suction head which has at least one projecting annular seal on its suction side, the vacuum space or vacuum spaces enclosed by the annular seal or annular seals being connected to a main vacuum generator, and an emergency vacuum generator supplied by a battery being additionally provided, which emergency vacuum generator can be put into operation via an emergency switch. So that sudden falls in such a vacuum hoisting device can be avoided to the greatest possible extent, a pressure sensor (67) is allocated to the vacuum space or at least one of the vacuum spaces (13), which pressure sensor (67) is coupled to a fault indicator (69) in such a way that the fault indicator (69) is switched on in vacuum operation if a set limit pressure is exceeded. <IMAGE>
